A novel ligand-free, highlyefficient, and an inexpensive method has been developed by using ecofriendly, heterogeneous reusable copper fluorapatite (CuFAP) catalyst for the synthesis of diaryl ethers from the cross coupling reaction of the various substituted aryl halides (fluoride, chloride, bromide, and iodide) with the potassium salts of various substituted phenols in the presence of N-methyl 2-pyrrolidone

The present invention provides a safe charge control agent which exhibits an excellent negative chargeability and excellent dispersibility in and compatibility with binder resins, and is even applicable for col or toners. Specifically, the charge control agent consists of a naphthol derivative of formula [I]:
and a salt thereof, and an electrophotographic toner comprising the agent are provided.
A facile and rapid method for the synthesis of novel imidazole and benzimidazole aromatic acyclic nucleosides is described. Synchronous N-alkylation of imidazole or benzimidazole and potassium aryloxide with methylene iodide in the presence of triethylamine and a catalytic amount of tetrabutylammonium bromide (TBAB) in dry acetonitrile or acetone gave moderate yields of the acycloaromatic nucleoside

Systematic ligand variation in a structurally conserved framework of pentavalenturaniumcomplexes of the formulas UVX2[N(SiMe3)2]3 (X = F, Cl, Br, N3, NCS, 2-naphthoxide) and UVOX[N(SiMe3)2]3– (X = −CCPh, −CN) allowed an investigation into the role of the inverse trans influence in pentavalenturaniumcomplexes. The −CCPh and −CN derivatives were only stable in the presence of the trans-U═O multiple
